To teach her boyfriend a lesson in humility, and to generally avenge all the female students for "unreturned phone calls and unrequited loves," [Diana Riggs] compels her school sisters to offer themselves as prizes in a competition between the two schools. Diana contrives a series of contests "divided equally between athletic and academic, so neither school will have an advantage." The winning school will have the exclusive right to take the young women of Miss Aversham's and Miss Cronstall's School for Girls to the annual prom. It's an irresistible offer, Diana says, because: "We're cute and sexy and above averagely smart."
